Abstract (en)
[origin: EP0519123A1] The present invention provides a method for making a lithographic aluminium offset printing plate comprising the steps of: information-wise exposing an imaging element comprising on an aluminium support a layer of physical development nuclei and a silver halide emulsion layer developing said information-wise exposed imaging element in the presence of a silver halide solvent to obtain a silver image in said layer of physical development nuclei and removing all layers on top of said silver image to expose said silver image by means of washing with rinsing water characterized in that said rinsing water has a pH of 4 to 8 and is bufferred. i
